Damn Small Linux (DSL) is a discontinued computer operating system for the x86 family of personal computers. It is free and open-source software under the terms of the GNU GPL and other free and open source licenses. It was designed to run graphical user interface applications on older PC hardware, for example, machines with 486 and early Pentium microprocessors and very little random-access memory (RAM). DSL is a Live CD with a size of 50 megabytes (MB). What originally began as an experiment to see how much software could fit in 50 MB eventually became a full Linux distribution. It can be installed on storage media with small capacities, like bootable business cards, USB flash drives, various memory cards, and Zip drives. DSL was originally conceived and maintained by John Andrews. For five years the community included Robert Shingledecker who created the MyDSL system, DSL Control Panel and other features. After issues with the main developers, Robert was, by his account, exiled from the project. He currently continues his work on Tiny Core Linux which he created in April 2008. DSL was originally based on Model-K, a 22 MB stripped down version of Knoppix, but soon after was based on Knoppix proper, allowing much easier remastering and improvements. DSL supports only x86 PCs. The minimum system requirements are a 486 processor and 8 MB of RAM. DSL has been demonstrated browsing the web with Dillo, running simple games and playing music on systems with a 486 processor and 16 MB of RAM. The system requirements are higher for running Mozilla Firefox and optional add-ons such as the OpenOffice.org office suite. version 4.4.10 of DSL, released November 18, 2008, was current.
